Introduction: Pain during and after surgery results in intense changes in hemodynamics, increased metabolic and endocrine stress hormone production, and increased myocardial oxygen demand and consumption. Some patients require bothopioid and non-opioid analgesics within the first 24 hours followingsurgery. Pre-emptive analgesia is theintroducing of analgesic management beforeonset of noxious stimuli, which helps to prevent pain potentiation. It provide spain relief priorto surgery and throughout the perioperative period. Bilateral superficial cervical plexus block (BSCPB) is a technique where local anaesthetic mixtureis injected based on anatomical landmarks. It reduces the intraoperative analgesic requirements when administered before surgery. By decreasing analgesic requirements, the block produces tableintra operative vital sin comparison to general anaesthesia alone [3] Therefore, this study involved administering bilateral superficial cervical plexus blocks for thyroid surgeries in addition to general anaesthesia, along with assessment of intra- and post-operative hemodynamics, evaluation of postoperative eanalgesia, and detection of adverse effects. Materials and Methods: This randomized study was carried out in the Department of Anaesthesia, MGM Medical College and MY Hospital, Indore, among 60 consented patients aged 18 – 60 years belonging to ASA grade I/II and posted for elective thyroid surgeries under general anaesthesia, allocated into 2 groups of 30 each: Group A (without SCPB) and Group B (with SCPB), using a proforma, pre-anaesthetic evaluation, investigations followed by induction of anaesthesia and performing of SCPB. Data was collected, compiled and analysed using SPSS 22.0 (trial version). Result: Majority Group A (36.67%) and Group B (40%) participants belonged to 31-40 years and 18-30 years age group, respectively and were females (Group A=90%; Group B=83.3%). Most were classified as ASA grade I (63.3%). The HR, SBP, DBP and MAP in Group A intra-operatively, was found to be significantly higher than Group B (p-value-0.000). Post-operatively, it was observed that the HR and SBP was significantly higher in Group A at all the time intervals till 24 hours after the procedure (p-value=0.000). The DBP was higher initially in the post-operative period in Group A (p-value=0.000), however, 24 hours later, it was found to be comparable with Group B(p-value>0.05). Similar was the case with MAP, which was higher in Group A in the initial post-operative period, decreased gradually and 24 hours later, was comparable with Group B(p-value>0.05). Statistically significant difference was also observed between both the groups (p-value<0.05) with respect to VAS score. Requirement of first rescue analgesia was earlier in Group A (p-value<0.000). Post-operative complication were experienced more in Group A. Conclusion: It was concluded that BSCB block with injection Ropivacaine 0.75% and injection Fentanyl 25 mcg was effective in blunting hemodynamic stress response to pain and provided stable hemodynamics throughout the surgery. It also reduced the dose and requirement of opioid analgesics after the surgery.
